Hereinafter, a method of manufacturing an ovate using a shellfish shell according to another embodiment of the present invention described above will be described in detail.

First, the above crushing step (S110) is to collect the washed shellfish shells, for example, waste oyster shell, and then to powder the naturally dried waste oyster shell into particles of 30 ~ 90 mesh through the grinder to dry the wash water Grinding step.

At this time, the size of the powder particles is preferably composed of a particle size of 30 ~ 90 mesh as described above so that the bonding with the binder is well made.

The organic material removing step (S120) is a step for removing the organic material contained in the powder of the shell shell pulverized by the grinding step.

That is, the organic matter removing step (S120) is to sinter the powder of the shell shells pulverized by the crushing step (S110) in the sintering furnace having an internal temperature of 500 ℃ ~ 800 ℃ 30 minutes to 60 minutes to remove the organic matter It's a step.

 At this time, when the powder of the shellfish shell is put into the sintering furnace and the sintering temperature is 500 ℃ or less, it takes a lot of sintering time. It is preferable to sinter in a sintering furnace having an internal temperature of.

The immersion step (S130) is a step of immersing the powder of the shell shells in silver nitrate or silver sulfate or silver perchloric acid solution.

That is, the immersion step (S130) is a powder of the waste shellfish shells from which the organic matter is removed by the organic material removing step so that the powder of the shellfish shells have antibacterial activity in the silver nitrate or silver sulfate or silver perchloric acid solution for 30 minutes to 1 hour 30 minutes Immersion step.

At this time, if the immersion time is too short, that is, immersed in less than 30 minutes, silver ions (Ag ⁺ ) will not penetrate into the powder, if immersed for more than 1 hour 30 minutes, it takes a long time during drying to decrease productivity Therefore, it is preferable to immerse for 30 minutes to 1 hour 30 minutes as described above.

The drying step (S140) is to dry the powder of the shell of shellfish shelled with silver ions by the immersion step (S130) for 2 hours to 5 hours in a dryer having an internal temperature of 80 ℃ ~ 100 ℃ Step.
